I don't think Gilbert will regret. I think LeBron made a business decision and now Gilbert is making a business decision. He needed to do something to keep interest from the Cavs fans and I think he really made a splash. He is stirring the nest, and giving something for the fans to rally around. Especially with the statement, "I PERSONALLY GUARANTEE THAT THE CLEVELAND CAVALIERS WILL WIN AN NBA CHAMPIONSHIP BEFORE THE SELF-TITLED FORMER ‘KING’ WINS ONE, You can take it to the bank."
He puts some pressure on himself now with comments like those, especially when a majority of the 'top' free agents have already landed. He needs to put together a solid, deep deep team with hard working studs who can just keep coming at ya.
On another note I agree with what is being said, Bron Bron's best shot at winning was Chicago, I think this Miami thing will blow up some how, unless they can find some solid veterans that are willing to take the league minimum and go join the circus. Personally I don't think it happens, I think people will do the opposite and try to pool talent to beat these guys.
